4.Professional technology and design teams, chart as customers' requirements.Â
Perfect and stable sine wave output The raw power from the Gasoline Engine is processed by a microprocessor into a clean stable sine wave of
electricity. This is important for anyone who wants to power sensitive
electronics such as computers, laptops, stereo receivers, HD
Televisions, electrical fan and precise electronic equipment. Use of
non-sine wave Power Generators (most conventional generators), may over time damage those equipment.
Strong combination load carrying ability
These series can endure high level of induction load and combination
load. The voltage and frequency are stable during both static and
dynamic process. Thus they are suitable for use at normal as well as
precise electronic equipment.
Low emission
A high-efficient combustion system produces exceptionally low emissions that meet GS emission standard.
Technical Features:
* Advanced and reliable, the air pressure requirement is not high
* Simple operation, high degree of automation, equipment for automatic unattended operation, quick start up
* Equipment operation and maintenance cost low
* Equipment operation and good stability, mature technology, reliable, and molecular sieve normal life can reach years
* The impurities such as gas component sulfide, ammonia and other industrial residue on common harmful substances can remove
* Product purity and yield of easy to adjust, and a strong ability to adapt
